Description
Technical Field
The utility model relates to a connecting assembly, belongs to the technical field of mechanical assembly, and particularly relates to a connecting assembly of a large-size high-precision rotary part capable of reducing the radial size of a rotary part.
Background
The rotary members (e.g., propeller blades and housings) are common members in the mechanical field, and large rotary members cannot be manufactured by integral molding, and the components must be manufactured separately and then assembled.
The traditional assembly mode of the rotary parts is generally welding or bolting, and the welding can cause local stress increase or thermal deformation, thereby seriously affecting the installation precision of the rotary parts.
The bolt connection is divided into three modes of bolt axial arrangement, bolt radial arrangement and bolt tangential arrangement, wherein the three bolt connection modes all need to be provided with a larger blade root at the lower part of the blade, and meanwhile, the bolt axial arrangement mode can cause larger shearing force on the bolt when the rotary part moves, so that the rotary part cannot be applied to a large rotary part; in a radial arrangement of bolts, the diameter of the rotating member (e.g., the rotating shaft) needs to be much greater than the length of the bolts for strength; in the tangential arrangement mode of the bolts, a connecting table with the height larger than the diameter of the bolts needs to be arranged outside the rotary member; both of these methods result in a larger radial dimension and heavier weight of the rotating member.
Therefore, the conventional welding or bolting cannot be applied to large-size high-precision rotary parts with a limit on the radial size of the rotary member.
The utility model patent application with application number 202020807606.7 and application date 2020.05.14 discloses an adjustable propeller adjusting assembly, which comprises: the rear end of the stern shaft is provided with an adjusting hole; the propeller hub is arranged at the rear end of the stern shaft, and a guide hole is formed in the rear end of the propeller hub; the fixing device is detachably arranged in the guide hole; the adjusting rod is arranged in the paddle hub, and a clamping hole is formed in the rear end of the adjusting rod; the front end of the adjusting rod is in threaded connection with the adjusting hole, and the front end of the fixing device is inserted into the clamping hole and is suitable for fixing the adjusting rod. While such an adjustment assembly simplifies the internal structure of the propeller, the design still suffers from the following drawbacks:
the fixing device and the propeller blade are positioned on the same radial plane of the revolving body, so that the radial dimension of the revolving body is larger.
The disclosure of this background section is only intended to increase the understanding of the general background of the application and should not be taken as an admission or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art.
